ABSTRACT:
An apparatus for processing an image with a discrete wavelet transform is provided. For one-dimensional circuit, the method changes conventional image data processing flow and uses common product of sequential calculations with respect to the time axis. The calculations for input data are not repeated so that components of the hardware architecture are minimized. For two-dimensional circuit, the method uses an external data scanning method to eliminate an external memory, transposing buffer, from a transforming circuit.
